冷热原油交替输送研究现状与展望

Progress and Prospect of Research on the Alternative Transportation of Cold-hot Crude Oil

冷热油交替输送是符合我国国情的一种输送工艺,具有很大的研究价值。我国的研究起步相对较晚,经过几十年的努力,取得了很好的成果。介绍了冷热油交替输送中管道土壤传热、管内非稳态传热流动研究的常用几种方法以及耦合计算的数学模型、求解步骤和原理,分析了近年来国内冷热油输送技术的成果。最后,结合国内的研究进展,对今后的研究做了展望。

Alternative transportation of hot-cold crude oil is a process in accord with China＇s national conditions. It has great research value. The research of the process in our country starts relatively late, but after decades of hard work, we have achieved good results. In this paper, some common research methods of soil heat transfer and unstable heat transfer in cold-hot oil alternative transportation were introduced. The mathematical model, the solving process and the principle of the coupling calculation were established and introduced. The achievements of domestic alternative transportation technology in recent years were analyzed.
